This is not surprising.

Funding, promotions, and political rewards tend to go to showy security that people can see and say ‘we feel safer because xyz is visible’.  Training is something people can not see and thus it tends to get little funding or attention.

Classic side effect of ‘security theater’ at work.

The fact is there is no perfect security. Trying for total security is only assured road to dictatorship and oppression. All of Homeland Security is more dangerous to the Bill of Rights and our supposed freedoms than it is to malfactors.

Who gets hired and who wants to get hired to boss around the average Joes and Joans? The very nature of these jobs encourages abuse and extortion and renders the average citizen defenseless against terror and their own government and police.

We never needed a faschist Homeland Security Department. Our various policing departments had the information using ordinary investigation technics, it was politically motivated department heads who blocked or avoided acting on the “intellegence” we had about the 9/11 terrorists. A mega security department is better at defending their own interests than the freedom or safety of the nation.

Standing armies are always more danger to the citizens than to the enemies of the country.

Infiltrated? We’ve come a long way folks, these Federal buildings (some years ago) may have had a guard or two milling about, but generally the public could enter, even use the bathroom or something. But since we’ve all decided the world is sick and dangerous and oh “Look at what that guy did on the NEWS!”
we venture down the heroic path of the police state without a clue of how we drifted to a state of armed, barricaded, security cleared impenetrable bunkers where priveleged power and millionaire Defense Contractors run things on our behalf. It was a sad day to see big steel fences surround NIH in Bethesda after 2001, but now everyone feels “safer” They’ve forgotten something, something really basic.
